Constants are declared in the ''Constants ... End Constants'' section of the model file. The constants may be defined in one section or in multiple declarations throughout the model. Parameter initialization is performed sequentially, from top to bottom. If a parameter does not have an initial value given, a default value of 1.0 is assigned. Constants may also be a function of other constants or variable initial conditions. These initial conditions are processed once as the first step after the model parsing.

Constants are fixed values that represent model inputs, fixed constants, or any other value that does not change. Constants are not modified by the solver as it searches for a solution. As such, constants do not contribute to the number of degrees of freedom (DOF).
